Shared Memory for CrewAI - Unison Integration

Give a CrewAI crew persistent shared memory: every agent reads the same project facts, and nothing is re-learned between runs.

Learn how to give a CrewAI crew persistent shared memory — so every agent reads the same project facts, and nothing is re-learned between runs.

CrewAI's built-in memory is per-crew and per-machine. Unison sits above it: one brain that every crew, run, and teammate shares.

There's no dedicated CrewAI package yet — recall and persist are two HTTP calls, so a small consistent helper keeps the example self-contained:

import httpx, os

BRAIN = os.environ.get("UNISON_API_URL", "https://brain.unisonlabs.ai")
HEADERS = {"Authorization": f"Bearer {os.environ['UNISON_TOKEN']}"}

def recall(query: str) -> str:
    ctx = httpx.get(f"{BRAIN}/v1/brain/context", params={"q": query}, headers=HEADERS).json()
    return "" if ctx["weakEvidence"] else ctx["contextMd"]

def remember(turns: list[dict], source_ref: str) -> None:
    httpx.post(f"{BRAIN}/v1/brain/ingest", headers=HEADERS, json={
        "items": [{"type": "conversation", "turns": turns,
                   "sourceRef": source_ref, "visibility": "workspace"}]
    })

Wire it into a crew

from crewai import Agent, Task, Crew

goal = "Draft the Q3 pricing update"
memory = recall(goal)

analyst = Agent(
    role="Pricing analyst",
    goal=goal,
    backstory=f"You build on what the team already decided.\n\nTeam memory:\n{memory}",
)
task = Task(
    description="Propose the Q3 pricing change with rationale.",
    agent=analyst,
    expected_output="A short pricing memo",
)
crew = Crew(agents=[analyst], tasks=[task])

result = crew.kickoff()
remember(
    [{"role": "user", "content": goal},
     {"role": "assistant", "content": str(result)}],
    source_ref="crew-q3-pricing",
)

Every agent in the crew shares the recalled context (inject it into the backstory or the task description); remember writes the outcome to the workspace so the next crew — on any machine — starts from it. Crews pointed at the same workspace share one memory automatically.
